A few experimenters have carried the verification much further.
Messerschmidt, editor of the best collection of Hittite texts up to date, made a tabula rasa of all systems of decipherment, asserting that only one sign out of two hundred the bisected oval, determinative of divinity - had been interpreted with any certainty; and in view of this opinion, coupled with the steady refusal of historians to apply the results of any Hittite decipherment, and the obvious lack of satisfactory verification, without which the piling of hypothesis on hypothesis may only lead further from probability, there is no choice but to suspend judgment for some time longer as to the inscriptions and all deductions drawn from them.
For some engineering purposes it would appear to be desirable to produce master-screws to an accuracy of (1/2000)th of an inch to the foot of screw, so as to serve indirectly for the verification of "guiding screws" for general use in workshops.
In the department of abdominal disease progress has been made, not only in this enormous extension of means of cure by operative methods, but also in the verification of diagnosis.
The experimental verification of the change of wave-length due to a source moving in the line of sight has been realized in the laboratory by A.
